Abstract
An attachment system joining the side edges of adjacent display panels. Each panel has first and second side edges, the first side edge of one panel joinable with the second side edge of an adjacent panel. The first and second side edges comprise first and second frame members affixed to the panel body. The first and second frame members are substantially identical, being coextensive and having outer faces with corresponding abutment surfaces thereon. Each first and second frame member has a longitudinal opening extending from its upper end through its lower end. Each first frame member has in its outer face a slot at its lower end communicating with its longitudinal opening and at least one bore. Each second frame member has, extending from its forward face, a headed stud near its bottom end, and at least one alignment stud. A U-shaped latch member has a handle position, a short leg and a long leg. The long leg is captively mounted in the opening of the first frame member at its upper end, being vertically shiftable and rotatable therein. When the first frame element of a panel is joined to the second frame element of an adjacent panel, the second frame element headed stud is received in the first frame element slot and opening; the at least one second frame element alignment stud is received in the at least one first frame element bore; and the latch member is lifted and rotated and the short leg is inserted into the second frame member opening, completing the attachment.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
